There are actually quite a few side effects related to excessive Vitamin C consumption. Your digestive tract will probably be the first thing to notice that something isnt right.

Common side effects include nausea, vomiting, heartburn, and esophagitis. You may also notice stomach cramps, diarrhea or intestinal obstruction.

September 4, 2020 By Trudy Scott

Supplemental vitamin C has many exceptional health benefits and causes no issues for a large majority of individuals. However if you have dietary oxalate issues, doses of vitamin C above 100mg to 250mg per day may be problematic and trigger pain, anxiety, insomnia, bladder issues and more. This blog, Coronavirus and vitamin C for immune support: new pain or more severe pain due to oxalate issues?, is part 1 of the series which sets the scene and is a fact-finding article. Part 2, Oxalate crystal disease, dietary oxalates and pain: the research & questions , covers the research behind oxalate crystal disease.

Today we look at some of the research on vitamin C/ascorbic acid being a possible trigger for the formation of oxalates in certain instances. This paper, No contribution of ascorbic acid to renal calcium oxalate stones, has a good summary:

This paper does however have this precaution:

Recurrent stone formers and patients with renal failure who have a defect in ascorbic acid or oxalate metabolism should restrict daily vitamin C intakes to approximately 100 mg.

Strong Nerves With Vitamin B1

You probably already know vitamin B1 as a mood vitamin. There is a reason for this, because thiamine is basically very important for the carbohydrate metabolism and the associated energy production.

Good carbohydrates can be found mainly in oat flakes.

The answer to the question of whether vitamin B can be overdosed is quite simple: overdosing via the normal food intake is ruled out. If there is an excess of vitamin B, it is usually excreted via the kidneys. So you do not need to worry about this!

If an overdose should occur, then only through the excessive intake of food supplements. So if you want to take supplements, check with your doctor before you do so and nothing can go wrong!

It’s that time of year. Your professor cancels class, your roommate is coughing nonstop, and the kid next to you in the library has a mound of used tissues piling up uncomfortably close to your laptop. You wash your hands and disinfect the doorknobs, but sometimes getting sick is just inevitable.

This is why when I felt that familiar feeling of the beginning of sickness, I decided that a healthy dose of vitamin C might help. Thus, my vitamin C bender day began. I started with an Emergen-C packet, followed by a glass of OJ at brunch, a green juice for a late afternoon treat, an immune booster tablet with dinner, and a smoothie for dessert. By my calculations, I had about 2,000% of my daily value of vitamin C.

However, after lying in bed for over two hours, I realized that I hadn’t yet fallen asleep. I tried deep breathing and lavender oil , but after another restless hour, I knew sleep just wasn’t in the cards. Coming from someone who can fall into REM sleep in an airport, I knew this bout of insomnia wasn’t normal.

In a 4:30 am haze, I googled “is too much vitamin C bad?” I browsed web page after web page detailing the various symptoms of consuming too much vitamin C. Sure enough, insomnia was listed as one of the many side effects.

There Are Some Lifestyle Changes That Might Be Making Many Of Us Deficient In Vitamin D

Our modern lifestyles may be to blame for an increase in vitamin D deficiency of all ages, according to Dr. Glatter. âWe are seeing more vitamin D deficiencies likely due to people spending more time indoors, but also using more sunscreen when spending time outside,â he said.âAccording to a 2012 Spanish study, 70% of adults donât have sufficient levels of vitamin D,â he said, adding that âlow levels of vitamin D have been associated with depression in adults, as well as mood variability and ADHD in children. Vitamin D supplementation is associated with better quality of life and well-being as we age.â

Americans are no better off in fact, Dr. Burrell added that âmost of the United States does not get strong enough sunlight during the winter months to boost vitamin D adequately. Additionally, as more people work in offices along with the increasing concerns surrounding sun damage to the skin, premature aging and skin cancer, sun exposure is not always the right answer to boost vitamin D.â

While it might seem like the easy answer is to spend more time outdoors, the risk for sun damage and skin cancer is high no matter what the temperatures are like outside. You need to wear sunscreen and sun protective clothing if youâre going to be outdoors for any extended length of time.
